/**
 * This Enum defines the multiple strategies the stack can use to clean 
 * more or less aggressively the references in order to win both memory 
 * and CPU cycles.
 * 
 * 
 * None: This is the default. It keeps references to request and responses as part of transactions and dialogs. This consumes the most amount of memory usage
 * Normal: It removes references to request and responses in transactions and dialogs in cleaning them up but keep byte arrays of requests or responses to be able to reparse them if the application need them. This gives a 2x improvement in memory as opposed to None
 * Aggressive: It removes references to request and responses in transactions and dialogs in cleaning them up and don't allow reparsing. Need careful application design. This gives a further improvements in memory as opposed to Normal Strategy and also CPU improvements.
